禁用在fragmentPagerAdapter中滑动？ - android

嘿家伙我有一个fragmentPagerAdapter,里面有3个片段.如何禁用3个片段之间的滑动,以便用户只使用tabview在片段之间进行？

干杯!

private class ViewPagerAdapter extends FragmentPagerAdapter
{
    ArrayList fragments = new ArrayList<>();
    ArrayList tabTitles = new ArrayList<>();

    public ViewPagerAdapter(android.support.v4.app.FragmentManager fragmentManager)
    {
        super(fragmentManager);
    }
    @Override
    public Fragment getItem(int position)
    {
        return fragments.get(position);
    }
    @Override
    public int getCount()
    {
        return fragments.size();
    }
    @Override
    public CharSequence getPageTitle(int position)
    {
        return tabTitles.get(position);
    }
    public void addFragments(Fragment fragment, String titles)
    {
        this.fragments.add(fragment);
        this.tabTitles.add(titles);
    }
}

您可以像这样设置自定义视图寻呼机: -

public class LockableViewPager extends ViewPager {
    private boolean swipeable;

    public LockableViewPager(Context context) {
        super(context);    
    }    

    public LockableViewPager(Context context, AttributeSet attrs) {    
        super(context, attrs);    
        this.swipeable = true;    
    }

    @Override    
    public boolean onTouchEvent(MotionEvent event) {    
        if (this.swipeable) {    
            return super.onTouchEvent(event);    
        }    
        return false;    
    }

    @Override

    public boolean onInterceptTouchEvent(MotionEvent event) {
        if (this.swipeable) {
            return super.onInterceptTouchEvent(event);
        }
        return false;
    }

    public void setSwipeable(boolean swipeable) {
        this.swipeable = swipeable;
    }
}

然后在布局中,您可以将其设置为: -

然后打电话

setSwipeable(false)

希望能帮助到你.

这里有一些关于LockableViewPager类示例的详细说明......

首先,而不是像这样标记一个ViewPager

你想创建一个像这样继承VP的自定义类

public class LockableViewPager extends ViewPager {
  private boolean swipeable;

  public LockableViewPager(Context context) {
      super(context);
  }

  public LockableViewPager(Context context, AttributeSet attrs) {
      super(context, attrs);
      this.swipeable = true;
  }

  @Override
  public boolean onTouchEvent(MotionEvent event) {
      if (this.swipeable) {
          return super.onTouchEvent(event);
      }
      return false;
  }

  @Override
  public boolean onInterceptTouchEvent(MotionEvent event) {
      if (this.swipeable) {
          return super.onInterceptTouchEvent(event);
      }
      return false;
  }

  public void setSwipeable(boolean swipeable) {
      this.swipeable = swipeable;
  }
}

注意这个方法

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
  if (this.swipeable) {
      return super.onInterceptTouchEvent(event);
  }
  return false;
}

然后,您可以标记已充当ViewPager的自定义类,并拦截触摸事件

在您的activity的包含LockableViewPager的java类中

LockableViewPager viewPager;
OnCreate() {
  viewPager = (LockableVewPager) findViewById(R.id.*id of pager*);
  viewPager.setSwipable(false);
}

扩展您想要的类(即ViewPager)是正确的方法,除非您正在创建一个完全不同的类,行为方式不同;*祝你好运
